SPECIFICATION forming part of Letters Patent N0. 276,407, dated April 24, 1883. Application filed December 30, 188:2. (No model.)

To all whom it may concern: g

Be it known that I, WALTER S. HOKE, a citizen ofthe United States, residing atPhiladelphia, in the county of Philadelphia and 5 State of Pennsylvania, have invented certain new and useful Improvements in Umbrellas; and I do hereby declare the following to` be a full, clear, and exactde'scription ot the invention,reference being had to the accompanying 1o drawings, which form part of this specitication, in which- Figure 1 is a 'side elevation of umbrella stick, runner, and notch. Fig. 2 isa side elevation of runner. Fig. 3 isa verticalsection' 15 through stick and notch. Fig. ellis a side elevation of collar.

My invention has for its object to provide means for locking or retaining an umbrella in its open and its closed positions, respect- 2o ively,'withoutthe employment of the springs ordinarily used for that purpose, and which involve the weakening of the umbrella-stick.

My improvements consist in the peculiar construction of the runner and the notch and 25 the combination of said parts with eachother and with the umbrellastick, as hereinafter fully set forth and claimed.

Referring to the accompanying drawings, A indicates an umbrella-stick, having a runner,

`3o B, to which the lower ends of the stretchers are attached, and a notch, O, in which theinn'er ends of the ribs are secured in the usual manner. Said runner consists of a sleeve, d, with an annular fast collar, d', which encircles 3 5 its middle or at a point about midway between its ends. In this collar the ends of the stretchers are secured. The sleeve c1 has two flaring slots, e e', which extend, respectively, from the upper and lower edges toward the middle of 4o said sleeve. These slots terminate at their inner extremities in branches eze, one on either side. In Fig. l, I have shown double branches for both the slots c e'; but a single branch may only be provided for each slot, and in 4 5 such case the branch may be practically but a continuation of the slot, the latter being curved substantially as shown in Fig. 2. The branches are for the recept-ion of the pins f j" on the stick A, and the slots are the entrances there- 5o to. When the pin f is in the branch ef the umbrella is held closed, und when the pinj'is in the branch c2 the umbrella is held open. To cause the stick-pins to enter the slots c c and thence the branches, the runner is slid alongthe stick and then slightly turned or ro- 55 tatcd on its longitudinal axis. lo withdraw the pins .the motion is reversed-ile the stick iswtirst slightly turned, and afterward the runner is slid thereon.

To permit the stick to be turned, and yet so tolimit the extent of its rotation as to keep the pins thereon substantiallyaligned with the slots the runner, thenotch or crown C is constructed as follows:

G represents a cylinder or tube, which is made fast to the stick, so as Io turn with the latter. Said tube has two annular ribs or langes,c c', respectively, one of which at least may be integral with the tube. Between these anges, and fitted in the annular groove which they form ou the tube, is a loose collar, c2, or a collar fitted so as to swivel or turn freely on the tube O or permit the latter tn be rotated within it. To said collar the notch proper or` crown O2 is securely fastened; or said collar and crown may be integral. The crown receives theinner ends ofthe umbrella-ribs.

The, collar c2 is formed with shoulders ci 04,' produced by cutting a recess, c5, in its lower edge. The tlan ge c' has also two shoulders, c6 c7, which are the sides ot' a projection, ci. When the stick is rotated, carrying with it the tube C', one of the shoulders c3 c4 meets one ot the shoulders c6 c7, said shoulders thus forining stops and limiting the rotation of the stick and preserving the alignment 0f the stick-pins with the runner-slots, so as to insure the ready and certain entrance of said pins to said slots.

`There is thus a community of operation between the runner, the notch, and the stick, the latter being rotatable inside of said runner and notch, and the notch limiting the rotation of the stick so as to preserve the alignment of its pins with the runner-slots.

lnasmuch as the stick is free to be rotated within the runner, (the latter not being designed to be rotated,) when said runner is slid along the stick, the latter will be automatically rotated,r when one of its pins enters one of the slots in the runner, by reason of rocl the :impingement of the pin against the4 inclined side of the slot, and said pin will be guided into the branch at the inner extremity of the slot, which branch will form the bearing or rest for said pin. The wide ends ofthe runner-slots are of such extent and the rotary movement9 of the stick is so limited by the stops on the notch that the stick can never be turned so far as to get its pins out of alignment with the slots. Hence, in opening and f closing the umbrella, after turning the stick by., said notch, substantially as shown and Vset forth. l v

2. The notch C, comprising a tube, C', with flanges or annular ribs c c', and a loose collar, c2, with stops, substantially as shown and set forth.

3. The combination of an umbrella-stick having locking or catch pins, arunnerhaving branched slots for the engagement ofsaid pins, and a notch having an internal tube to which the stick is fastened, and a swiveled collar, said tube and collar having stops for limiting the rotation of vthe former Within the latter, so as to maintain the alignment of the stickpins with the runner-slots7 substantially as shown and set forth.

4. An umbrella-notch consisting of a collar and sleeve, the latter being swiveled in the former and having the extent of its rotation limited by stops, substantially as shown.

5. The combination of an umbrella stick, slide, and notch, said several parts being constructed as follows: the notch composed of a collar and a sleeve swiveled therein and limited in its rotation by stops, the stick secured to said sleeve and having locking-pins, and the slide having notches into which the stickpins enter, whereby the stick is locked and unlocked 'by turning it in the slide, the notchsleeve rotating with said stick, and the notchcollar and slide remaining stationary with respcct to such rotation, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of December, 1882.
